This is known error.

Some libraries have not done anything (google/gson#924) other ones have implemented workaround (ReactiveX/RxJava#3459).

Couple of stacktraces from my project:
com.mirrorai.app_issue_crash_5D5E4CFA0353000119B5FCFF34F93B11_DNE_0_v2.txt
com.mirrorai.app_issue_crash_5D61DBF600A40001134DD9BDD9BD8B29_DNE_0_v2.txt

I'm not convincing you to implement workaround like RxJava did but i think that at least it will be convenient to keep this issue to prevent questions from other users of coroutines library.

Proguard is turned off.

Coroutines version is 0.24.0.
Kotlin version is 1.2.60.
